PI6C20800
Description
PI6C20800 is a high-speed, low-noise differential clock buffer
designed to be a companion to PI6C410B. The device distributes
the differential SRC clock from PI6C410B to eight differential
pairs of clock outputs either with or without PLL. The input
SRC clock can be divided by 2 when SRC_DIV# is LOW. The
clock outputs are controlled by input selection of SRC_STOP#,
PWRDWN# and SMBus, SCLK and SDA. When input of either
SRC_STOP# or PWRDWN# is LOW, the output clocks are
Tristated. When PWRDWN# is LOW, the SDA and SCLK inputs
must be Tristated.
